2 • ERCB Directive 081: Water Disposal Limits and Reporting Requirements for Thermal In Situ Oil Sands Schemes (November 2012)

1 Purpose of this Directive

This directive consolidates various aspects of water management requirements for thermal in situ oil sands operations. It sets water disposal limits and includes detailed requirements for reporting injection facility water streams to PETRINEX to ensure that Energy Resources Conservation Board (ERCB) facility water balance requirements are met. The disposal limits requires operators to recycle produced water efficiently and ensure that make-up water is effectively used. Efficient water treatment, recycle, and disposal at thermal operations will optimize overall water use and energy efficiency.

In addition to limiting disposal, this directive provides formulas—for water make-up, water productivity ratios, and produced-water recycle—that will be used for monitoring and comparing thermal operations in Alberta. These formulas, along with scheme volumetric data, will be published on the ERCB website.

The ERCB will review the requirements of this directive regularly and may revise requirements as a result of

• improvements in water treatment, recycle, and steam generating technology;

• changes introduced by operators to field operations and water handling;

• changes in bitumen recovery technology that impact water treatment, recycle, and disposal;

• policy and regulatory changes introduced by other government agencies; and

• alignment with other ERCB directives.

The ERCB has also compiled and defined a list of terms used in this directive to provide clarity and to make the information in the directive more accessible (see Appendix A).

2 What’s New in this Directive?

This directive

• replaces Bulletin 2006-11: Water Recycle, Reporting and Balancing Information for In Situ Thermal Schemes, and

• supersedes and replaces Informational Letter (IL) 89-05: Water Recycle Guidelines and Water Use Information—Reporting for In Situ Oil Sands Facilities in Alberta.

The following table lists the requirements in this directive and the reason for their inclusion.


Table 1. What’s New in This Directive? Requirement This directive Prior to this directive Injection facility water balance

Specifies a maximum monthly facility imbalance (see section 4.1). Specifies requirements for conducting a monthly water balance on a thermal in situ injection facility (see Appendix B).

ERCB Directive 017: Measurement Requirements for Oil and Gas Operations does not set a maximum facility imbalance for water. The ERCB methodology, rules, and equations used in conducting a water balance on thermal in situ injection facilities could be found in various documents and were made available in meetings with stakeholders.

Exemption from water recycle

Sets a maximum disposal limit for all thermal in situ oil sands schemes where the total water make-up exceeds 500 000 cubic metres (m3) annually in the absence of produced-water recycle (see section 5).

IL 89-5 required thermal in situ schemes to recycle produced water if fresh water demand exceeded 500 000 m3 annually and actively investigate and test recycle technology if demand was under 500 000 m3 annually.

Disposal limit formula Optimizes produced-water recycle by limiting disposal based on the quantity of fresh, brackish, and produced water used at the central processing facility (see section 5 and Appendix C).

Most thermal commercial scheme approvals required a minimum annual produced-water recycle rate based on the formula in Bulletin 2006-11. The recycle formula did not account for make-up water sources other than those that are fresh.

3 ERCB Requirements and Compliance Assurance

Requirements in this directive are those rules that a thermal in situ oil sands operator is required to follow. The term “must” indicates a requirement, while terms such as “should” and “encourages” indicate a recommended practice.

Noncompliance with any risk-assessed requirement in this directive will result in the operator receiving a response in accordance with the latest edition of ERCB Directive 019: Compliance Assurance. Some examples of noncompliance for which the ERCB will take enforcement action are if

• actual water disposal at the scheme exceeds the disposal limit,

• the monthly injection-facility water balance closure is greater than 5.0 per cent for three consecutive months, or

• fresh water is reported as brackish water in PETRINEX.

The ERCB encourages all in situ oil sands operators to be proactive by monitoring their compliance with this directive. If an operator identifies a noncompliance, it should inform the ERCB of the noncompliance for consideration under the ERCB Voluntary Self-Disclosure policy set out in Directive 019. For a list of noncompliant events and further details on compliance assurance, including Directive 019 see the ERCB website www.ercb.ca/safety-and-compliance/compliance-enforcement.

3.1 Compliance with Disposal Limit

For the first twelve months of scheme start-up, the ERCB will not strictly enforce the disposal limit (see section 5). The start-up period is from the commencement of steam injection. Once this twelve-month period is complete, the ERCB will use the remaining

http://www.ercb.ca/safety-and-compliance/compliance-enforcement

http://www.ercb.ca/safety-and-compliance/compliance-enforcement


months of that calendar year to calculate the disposal limit to determine compliance for that year. The start-up grace period does not apply to scheme expansions.

The ERCB will consider variations of the disposal factors in Table 2 of section 5 upon application in cases where high produced-water rates or high concentration of total dissolved solids (TDS) in make-up water make it difficult to meet the disposal limit (e.g., water-to-steam ratio exceeds 1.05 or TDS exceeds 15 000 mg/L). It is the operator’s responsibility to justify any deviation from the requirements in section 5.

4 Water Reporting and Facility Water Balance

4.1 Injection Facility Monthly Water Balance

The ERCB equation for monthly water imbalance on an injection facility is provided in Table B3 of Appendix B. This monthly imbalance will correspond to the balancing activity “DIFF” for the product group “WATER” in the “Summary” view for an injection facility in PETRINEX. The monthly imbalance must not exceed 5.0 per cent for three consecutive months or more.

Accurate water measurement is needed in order to meet the injection facility monthly imbalance requirement and to reliably calculate the disposal limit (section 5.2) and actual disposal (section 5.3). Water measurement requirements for thermal in situ oil sands operations are set out in sections 12.3 and 12.4 of Directive 017: Measurement Requirements for Oil and Gas Operations.

4.2 Reporting to PETRINEX

Operators must report monthly water streams to PETRINEX in accordance with the definitions and equations in Appendix B.

The data are used by the ERCB to determine compliance with the maximum injection facility imbalance of 5.0 per cent (see section 4.1) and with the annual scheme disposal limit (see section 5 and Appendix C). The correct reporting of water is also necessary in order to monitor and evaluate the performance of each scheme. To help ensure that water volumes are correctly reported to PETRINEX, examples of the required PETRINEX reporting of water and the required water balance calculations have been included in the appendices of this directive and are described below. For each example, the steam volume is reported in cold water equivalent.

1) Appendix D provides a simplified water-flow diagram with PETRINEX reporting codes and required metering for a sample thermal scheme. The appendix also illustrates the boundary between a battery and injection facility for the purpose of reporting to PETRINEX (i.e., produced water leaving a battery requires no further hydrocarbon separation.)

2) The required reporting of the sample scheme water volumes from Appendix D to the correct PETRINEX codes is provided in tabular form in Appendix E.

3) Appendix F displays the resulting PETRINEX screen shots for the sample scheme facilities in Appendix D to illustrate what the “Summary”, “Facility Activity”, and “Well Activity” views of PETRINEX would look like for the reporting requirements in Appendix B.

http://www.ercb.ca/regulations-and-directives/directives/directive017


4) For the same sample scheme facilities, Appendix G shows how the correctly reported water volumes from PETRINEX are used to generate a monthly water balance, using the required equations from Table B3, Appendix B.

5 Formulas and Limits for Disposal at Thermal In Situ Schemes

This section establishes a maximum water disposal limit for each thermal in situ operation in Alberta. The maximum disposal limit is intended to ensure efficient recycling of a scheme’s produced water and to promote energy efficiency.

Effective immediately, the maximum water disposal limit applies to all new schemes. For existing schemes, the maximum water disposal limit will become effective either

• when the licensee applies to expand a scheme’s bitumen processing or steam generation capacity (applied to the entire scheme within the time frame stated in the approval), or

• three years from November 21, 2012, unless a shorter period is applied for by the operator.

The effective date of the maximum disposal limit will be whichever date occurs first.

The limits set out in this section do not apply to thermal in situ oil sands schemes that, in the absence of produced-water recycle, have a total annual volume of make-up water less than 500 000 m3.

5.1 Overview

Water disposal at a scheme is affected by

• the quality and quantity of water streams entering the facilities in the scheme,

• the treatment technologies being used, and

• the bitumen recovery mechanism.

Based on available technologies and bitumen recovery mechanisms, the ERCB has established a disposal allowance for each type of water used at thermal operations. These allowances are entered into the disposal limit formula to determine the maximum disposal limit for the scheme (see section 5.2).

The maximum disposal limit will be enforced against the total annual (calendar year) volumes of water disposal at each scheme. Formulas must be applied on a scheme basis. Schemes with multiple injection and disposal facilities cannot apply these formulas to individual facilities.

For the purpose of this directive, the water types used in the disposal-limit formula are fresh, brackish, and produced, with the recovery mechanisms being steam-assisted gravity drainage (SAGD) and cyclic steam stimulation (CSS). If water types, recovery mechanisms, or treatment technologies change, this directive and its limits will be amended accordingly.

For disposal formulas using ERCB water balance codes, see Appendix C.


5.2 Disposal Limit Formula

The maximum disposal limit for a scheme is calculated as a percentage of the scheme’s total inlet water volume:

100In ProducedInBrackish InFresh

pDIn x ProducedbDIn x Brackish fDIn x Fresh (%)Limit Disposal ×

++

++

=

where

Fresh In = the annual volume of inlet fresh water in m3 for the scheme from volumes reported in PETRINEX.

Brackish In = the annual volume of inlet brackish water in m3 for the scheme from volumes reported in PETRINEX.

Produced In = the annual volume of inlet produced water in m3 for the scheme from volumes reported in PETRINEX.

Df = the disposal factor for fresh water.

Db = the disposal factor for brackish water.

Dp = the disposal factor for produced water.

Table 2 provides the disposal factors for the recovery mechanism used in the scheme.

Table 2. Disposal factor by thermal in situ recovery mechanism Disposal factor Inlet water type SAGD CSS Df Fresh water 0.03 0.03 Db Brackish water 0.35 0.35 Dp Produced water 0.10 0.07

5.3 Actual Disposal Formula

The actual disposal formula gives the total scheme disposal as a percentage of the scheme’s total inlet water volume:

100InProducedIn Brackish InFresh

Disposal Total(%) Disposal Actual ×++

=

where

Total Disposal = the annual volume in m3 of scheme water injected into designated disposal wells and annual volume of scheme water delivered out of the scheme.

Fresh In = the annual volume of inlet fresh water in m3 for the scheme from volumes reported in PETRINEX.

Brackish In = the annual volume of inlet brackish water in m3 for the scheme from volumes reported in PETRINEX.

Produced In = the annual volume of inlet produced water in m3 for the scheme from volumes reported in PETRINEX.

The scheme’s actual disposal must not exceed the limit calculated by the disposal limit formula.


6 Data Publication

Coincident with the release of this directive, a new interactive publication—Thermal In Situ (TIS) Water Publication—of monthly and annual water usage at all commercial thermal in situ schemes is available on the ERCB website. The publication includes water disposal limits and actual water disposal (sections 5.2 and 5.3), and additional scheme performance indicators (Appendix H). The data used in the publication can be exported by users to an Excel spreadsheet. The publication may be amended from time to time to include additional performance indicators and data.

Appendix A Definitions

Battery A system or arrangement of tanks or other surface equipment receiving the effluent of one or more wells prior to delivery to market or other disposition, and may include equipment or devices for separating the effluents into oil, gas or water and for measurement.

Boiler blowdown Boilers used in thermal recovery processes typically produce steam with a quality between 75 and 80%. This results in 20 to 25% of the boiler feed water not being vapourized, and in steam-assisted gravity drainage (SAGD) schemes, the resulting liquid is separated from the steam. This separated water stream leaving the boiler is called blowdown and contains more concentrated total dissolved solids, typically 4 to 5 times more, than the boiler feed water.

Brackish water (saline groundwater)

For the purpose of this directive and for reporting to PETRINEX, brackish water is saline groundwater defined in Part 1(1)(z) of the Alberta Water (Ministerial) Regulation as “water that has total dissolved solids exceeding 4000 milligrams per litre.” Such groundwater is defined as “brackish water” in PETRINEX and “saline groundwater” by Alberta Environment and Sustainable Resource Development.

Camp For the purpose of this directive, a camp is a residential housing facility for construction and operations workers associated with a thermal injection scheme.

Cold water equivalent (CWE)

All produced and injected water and steam volume measurements are corrected to a standard temperature of 15oC and 101.325 kilopascals absolute and reported in m3.

Existing scheme A scheme that has received ERCB approval before the issuance of this directive, even if not yet constructed.

Fresh water (nonsaline groundwater or surface water)

For the purpose of this directive and for reporting to PETRINEX, fresh water is either nonsaline groundwater, which is groundwater that has total dissolved solids less than or equal to 4000 milligrams per litre, or surface water, which is as defined in Part 1(1)(bb) of the Alberta Water (Ministerial) Regulation as “all water on the ground surface, whether in liquid or solid state.”

A freshwater source may refer to

• a well licensed by the ERCB drilled to a depth of greater than 150 m;

• a shallow well with a depth of less than 150 m;

• a surface water source, such as a diversion point at a lake or a river (regardless of TDS); or

• surface runoff collected.

Regardless of the source, all freshwater use requires a diversion licence from ESRD in accordance with the Water Act.

Injection facility A system or arrangement of surface equipment associated with the injection or disposal of any substance through one or more wells.


Make-up water Water used at thermal in situ operations other than produced water from wells within the scheme. This water must make up for water losses such as the disposal of water treatment waste streams, boiler blowdown, and reservoir retention of injected steam.

New scheme A scheme that did not receive ERCB approval before the directive was issued.

PETRINEX PETRINEX is a web-based system that provides management/exchange of volumetric, royalty, and commercial information associated with the upstream petroleum sector for the Provinces of Alberta and Saskatchewan.

Produced water Water that is produced in association with hydrocarbon production from a well that was licensed for the purpose of hydrocarbon production.

Scheme For the purpose of this directive, a scheme includes all batteries and injection facilities associated with an ERCB thermal in situ oil sands scheme approval.

Steam For reporting to PETRINEX, the sum of all steam injection of varying quality, reported in cold water equivalent.

Water balance A series of calculations the ERCB uses on water volume data that are reported to PETRINEX to give the ERCB an indication of measurement and reporting accuracy for a facility. The water balance identifies all water types and water uses, and determines the imbalance between the total input and total output streams.

Appendix H Additional Scheme Performance Indicators using ERCB Water Balance Codes

The ERCB uses the following formulas to assess scheme performance and to compare schemes. If multiple injection or disposal facilities exist within a scheme, values for all facilities must be summed. (e.g., BW1 = ∑ BW1 for all injection facilities).

1) Freshwater Productivity Ratio

ProductionBitumenFW5) - FW4 (FW1+

2) Brackish-Water Productivity Ratio

ProductionBitumenBW5) -BW4 (BW1+

3) Disposal Ratio

ProductionBitumenDIT

4) Freshwater Make-up (%)

100DIT) (INT

FW5) - FW4 (FW1×

++

5) Brackish-Water Make-up (%)

100DIT) (INT

BW5)- BW4 (BW1×

++

6) Produced-Water Recycle (%)

[ ] 100PW8)-PW5 - PW4 (PW1

DIT -PW8) - PW5 - PW4 (PW1×

++

The above formula for produced-water recycle assumes that all disposal (DIT) is from the produced-water streams. Since make-up water in the disposal stream is expected to be small and is usually not possible to track, this formula is a good approximation of the minimum produced-water recycle.
